Energy Department: World CO2 Emissions Rising Faster Than Ever

New figures released by the Department of Energy show that the world is emitting carbon dioxide at a rate much faster than scientists had predicted. Global CO2 emissions reached 10 billion tons in 2010, the Oak Ridge National Lab reports, about 564 million tons or 6 percent more than emitted in 2009. It's the biggest annual jump ever recorded thus far:

The new figure also means CO2 is now being emitted at a rate higher than the figure the Intergovernmental Panel on Climate Change (IPCC) used in 2007 to project its worst-case scenario for global temperature increase by the end of the century (depicted by the red line in the graph below):

In light of the new DOE report, the question scientists are asking now is whether the world will experience the IPCC's worst case scenario "or something more extreme," Christopher Field, a Stanford University professor and head of one of the IPCC's working groups, said.
